To all whom it may concern: 7

Be it known that I, Gnoncn LAING YOUNG,

a subject of the King of Great Britain and Ireland, and residing at 22 Roseberry Avenue, South Shields, 1n the county of Durham, England, have lnvented certain new Liquid-Fuel-Furnace Fronts, of which the following is a specification.

The invention relates to liquid-fuel furnace fronts and consists in the features hereinafter described and particularly pointed out in the claims.

In the accompanying drawings illustrating, by way of example, an arrangement embodying the invention, v

Figure 1- and Figure 2 show in axial sections the air regulator'of theapparatus in the fully open and fully closed positions;

Figure 3 and Figure 4 showin sections at right angles to Figures 1 and 2 parts ofthe burner tube and of the cover plate in different relative positions.

Figure 5 shows in axial section a modified form of furnace front in which both the airregulating cover plate and the burner tube are slidably supported on guide rods secured to the casing, while- Figure 6 shows in a similar sect-ion a furnace front in which the hub of a spider slidably supports the burner tube in its bore and the air-regulatin g cover plate on its outside.

Corresponding parts in the different fig- 1igres are denoted'by the same reference sym- The furnace front consists in the casing l in which is arranged the air cone 2 slidably mounted on the burner tube 3, the air cone and the burner tube being adjustable in any convenient manner as for instance by the handle bars 2 and 3 respectively. The air cone 2 carries oppositely disposed deflectors 2* designed to give a whirling motion to the incoming air.

The front cone of the casing 1 is truncated to form an air opening 1 and a cover plate 4 adapted to completely cover said air opening is axially movable on the guide bars 5 and carries slidably arranged in its hub the burner tube 3. The studs or guide bars 5 are provided at their free ends with collars or heads 5 thereby limiting the forward movement of the cover plate.

Thumb sc ews 6 ar provid d 11 he WW1 positions on the bars-5. a

plate so as to secure it in the adjusted posi-v tion onthe guide rods 5, The cover plate has an angularly'disposed projecting flange 4 so as to direct the air current well into the interior ofthe casing. A thumb screw 6 7 arranged on the hub of the cover plate 4 secures the latter in any desired position on the burner tube 3, so'that by manipulation oft-he handles'3 the cover platev and the burner are simultaneously operated; An 5 asbestos or likering 8' is arranged on the i I inside of the cover plate 4.*

In the form shown in Figure 5, the front ofv the casing which is constituted by the --cover plate 4 is supported, axially movable,

on guide bars 5. "These'bars 5 also support in frontof the cover plate 4, in an axially slidable manner, the'flange 3 of the burner tube '3, which is guided in the bore of the hub 4 of the cover plate 4; Set or thumb screws are provided for locking the cover plate and the flange 3 'in'their adjusted Inthe modification shown in Figure 6, a

spider 9'with an extended hub 10 is arranged in the front opening of the casing 1,

and carries slidably adjustable in the bore of said hub 10 the burner tube 3, which is prevented from rotating therein and locked in the adjusted position by means of the thumb screws 11 engaging grooves 3 in the burner tube, 3. On the outside of the hub 10 is slidably mounted the air regulating cover plate 4 which is further guided. on the bars 5 and locked thereon by means of thumb screws 6. One bar 5 onlyv may be provided or they may be dispensed with altogether, in which case thumb screws serving both the purpose of preventing rotation and of locking would be provided on the 96 hub of the cover plate 4 and adapted to engage grooves in the hub 10.

- The flange 4 of the cover plate 4 is formed in both figures as a truncated cone of approximately 45 having its apex at the rear 100 of the plate 4 and the front opening of the casing 1 is provided With a corresponding conical seating 1 for the flange 4 when the cover plate'is pushed home so that the furnace front is completely closed and air ad Having now described my invention, what I claim asnew and desire to secure by Letters Patent is 1. In combination, a casing, a cover plate therefor, a bi-co'nical air C9119 arranged within the casing, a burner tube passing through the cover plate and the air cone, means for slidably mounting the cover plate on the casing so that the cover plate may be moved axially thereof, means for slid- 3. An arrangement as claimed in claim 1, wherein the means for shdably: supporting the cover plate includes guides projecting longitudinally from the casing upon which the plate is slidably mounted, stops carried by the outer ends of the guides and vdevices ,adjustably engaged through the plate and frictionally engaged with the guides whereby to maintain the plate in the desired position of adjustment withrespect to the casing.

4:. In combination, an annular casing having the respective ends opened with one end adapted to communicate with the opening in a furnace guide rods extending longitudin ally from the other opened end of the casing, aco'ver plate slidably mounted on the guide rods and adjustable with respect to the casing, 21 bi-conical air cone arranged within the casing, rods extending from the bi-conical air cone and slidably arranged through the cover plate so as to adjustably support the cone within the casing, whirl producing collectors carried by said air cone, a burner tube "slidable centrally through the cover plate, and rods extending from the burner and also slidable through the cover plate to facilitate adjustment of the burner, substantially as and for the purposes set forth. v

5. An arrangement as claimed in claim 4, wherein handles are formed on the outer ends of the rod which project from the tube and the cone to facilitate relative adjustment with these parts with respect to each other and to the cover, stops formed on the outer ends of the guides, and-fastening devices arranged in the cover plate' and engageable with the guides for maintaining the cover plate in the desired position of adjustment with respect to the casing.

In testimony whereof I have signed my name to this specification.

GEORGE LAING YOUNG.
